Shutter Speeds

 Shooting info:

AV: 4.0
ISO: 1000
Focal Length: 24.0mm
 Shooting Info:
TV: 1/50
AV: 4.5
ISO: 500
Focal Length: 24.00mm
Shooting info:
TV: 1/10
AV: 5.6
ISO: 160
Focal Length; 24.0mm

Camera set up on tripod at fixed focal length.  Early evening on a grey day against dark building was limited light.  I've changed the ISO to try and keep the AV reasonable similar through the series of approx 24 shots at a range of shutter speeds from very fast to very slow.
I've selected three out of the series to highlight the difference.
At 1/160th the action of the cyclist is frozen. At 1/50th there is a sense of movement but the cyclist is still identifiable.  However at 1/10th the cyclist is now like a ghost passing by.  However this does give a greater sense of speed.
Timing is tricky for each of these. I was aiming to catch the cyclist in front of the wooden doors each time.
